Wild guess: Can I make use of this interface to query UBX-MON-HW3?
length = uUbxProtocolEncode(**0x0a, 0x37**, NULL, 0, pBuffer);
if (uGnssMsgSend(pObj->deviceHandle, pBuffer, length) == length)
{
messageId.type = U_GNSS_PROTOCOL_UBX;
messageId.id.ubx = 0x0a37; // This could be any UBX message ID/class
length = uGnssMsgReceive(pObj->deviceHandle, &messageId, &pBuffer, MY_MESSAGE_BUFFER_LENGTH, 30000, NULL);
Probably nothing at a PIO# or field level, the UBX-MON is more a a reporting/monitoring method.
Periodic output would be these:
0x20910354 CFG-MSGOUT-UBX_MON_HW3_I2C
0x20910355 CFG-MSGOUT-UBX_MON_HW3_UART1
0x20910358 CFG-MSGOUT-UBX_MON_HW3_SPI
Association of the PIO# tends to related to specific peripheral and functions, ie is the I2C enabled, which pair of pins are mapped. Which PIO# to use for TXREADY, GEOFENCE or Antenna Management.
Just want to make clear I understood the feedback Using a very basic query example: Say I want a command to send to the MIA 10 to query whether PIO5 is at a high or low level
Is it that there is no interface available to query the state of PIO5?
Please clarify... Thank you
If UBX-MON-HW3 has the information, you should be able to send a query form of the command, ie a packet with a zero length payload. It doesn't involve a configuration key. If you want a message with this data every couple of seconds, you can pace via the CFG-MSGOUT keys
There are other PIO related messages, but are not part of the public facing documentation.
Perhaps u-blox-M10 SPG 5.10 Interface description, UBX-21035061, NDA required, or FAE / INT level material.
Thanks for the feedback Could you please share a code snippet to send a query form? It would be for one time poll, I don't need to make it periodic Thank you
I'm not using ubxlib, I'd assume the byte code would look like this, and be sent like this
B5 62 0A 37 00 00 41 CD
uint8_t ubx_mon_hw3_query[] = { 0xB5,0x62,0x0A,0x37,0x00,0x00,0x41,0xCD };
uGnssMsgSend(pObj->deviceHandle, ubx_mon_hw3_query, sizeof(ubx_mon_hw3_query));
Got it, Looks like ubxlib has an encode API to generate ubx_mon_hw3_query uUbxProtocolEncode
To retrieve the response content, I see uGnssMsgReceive
Thanks,
Hello Rob, Question whether ubxlib has an interface to report status of the MIA M10 Gnss receiver, such as hardware status or I/O subsystem.
M10 interface Manual available here: https://content.u-blox.com/sites/default/files/u-blox-M10-SPG-5.10_InterfaceDescription_UBX-21035062.pdf?hash=undefined
Specific interest in accessing the I/O pin status as described by command 3.14.4 UBX-MON-HW3 (0x0a 0x37) as documented on page 86 on the interface manual
Several configuration values are defined under u_gnss_cfg_val_key.h https://github.com/u-blox/ubxlib/blob/master/gnss/api/u_gnss_cfg_val_key.h and this code https://github.com/u-blox/ubxlib/blob/master/example/gnss/cfg_val_main.c provides examples for using seemingly relevant uGnssCfgValSet and uGnssCfgValGet
But I am not able to find the keyId correlated to UBX-MON class?!?
Some guidance would be greatly appreciated
Thank you
